This is a sequel to my video on standard G versus Sawmill G tuning in which I look at using the Double C tuning for both major and modal tunes in the key of C.
I didn't mention this in the video but Gospel Plow is a good example of a C tune in the Dorian (mountain minor) mode, and Sally in the Garden is a good example of a C tune in the Aeolian (true minor) mode.
A tab that illustrates the modal scales played in this video is available on the Banjo Hangout: https://www.hangoutstorage.com/banjohangout.org/storage/tabs/s/tab-scales-for-comm-25270-17213522022.pdf
